I am working with Message Manufacturing Specification (MMS) in wireshark. The tool is unable to dissect the ACSE layer. It doesn't show any error but it shows the ACSE data as a part of MMS i.e., after the presentation layer, MMS is displayed. Kindly assist if there is a way for wireshark to distinguish both the layers.

Thanks.

This question is from 2012, but in 2016 Wireshark 2.2.0 is able to dissect ACSE (Association Control Service Element) in MMS PDUs. To test it, you can download MMS sample capture data from the Wireshark website and open it in Wireshark. You will see dissected ACSE such as:

ISO 8650-1 OSI Association Control Service
